果。另外，可以請(qǐng)求具有Excel格式的班級(jí)的出勤數(shù)據(jù)的電子郵件消息，同時(shí)在應(yīng)用程序中提供出勤結(jié)果的分析。b）學(xué)生申請(qǐng)：學(xué)生可以使用教3秒長的視頻來添加照片。如果出現(xiàn)錯(cuò)誤，可以刪除他們上傳的照片。學(xué)生只能看片和檢測(cè)到的肖像照片只能由老師訪問。如果學(xué)生在進(jìn)行出勤檢查時(shí)不在教室，則會(huì)通知他們出勤檢查。如果出現(xiàn)錯(cuò)誤（如果學(xué)生在場(chǎng)，但系統(tǒng)未檢測(cè)到他/她可以通知教師，以便他她可以解決問題。家庭申請(qǐng)：家長可以看到孩子每節(jié)課的出勤率。可以將其他子配置文件添加到系統(tǒng)中。每個(gè)父母都會(huì)添加到她的父母時(shí)，他們會(huì)自動(dòng)查看出勤結(jié)果。當(dāng)他們的孩子不在教室時(shí)，他們也會(huì)收到通知。3）通信層：RESTfulWeb服務(wù)用于在應(yīng)用程序和服務(wù)器層之間進(jìn)行通信。請(qǐng)求由POST方法發(fā)送。每個(gè)請(qǐng)求都使用會(huì)話的授權(quán)用戶的唯一ID發(fā)送。只有授權(quán)用戶才能訪問和響應(yīng)他們有權(quán)訪問的數(shù)據(jù)。由于其靈活性和快速性能，JSON被用作Web服務(wù)響應(yīng)的數(shù)據(jù)格式[8]。利用這種抽象的Web服務(wù)層，系統(tǒng)可以很容易地用于應(yīng)用層中的新項(xiàng)目，例如網(wǎng)頁或新的移動(dòng)操作系統(tǒng)。3）部檢測(cè)和識(shí)別算法，并且創(chuàng)建了30多種不同的Web服務(wù)，用于處理來自移動(dòng)應(yīng)用程序的不同請(qǐng)求。人臉檢測(cè)準(zhǔn)確有效的人臉檢測(cè)算法提高了人臉識(shí)別系統(tǒng)的準(zhǔn)確度。如果未正確檢測(cè)到面部，[9]。由于教室照片是在教師的控制下拍攝的，因此姿勢(shì)變化可能僅限于小范圍。使用Ada-boost訓(xùn)練的Viola-Jones面部檢測(cè)方法被視為實(shí)時(shí)課堂考勤系統(tǒng)的最佳選擇[9,10]。在最基本的意義上，首先根據(jù)某種算法找到并引入所需的對(duì)象。然后，他們被掃描以找到具有相似形狀的匹配[11].人臉識(shí)別[12]?；谔卣鞯姆椒ㄔ噲D將對(duì)象表示（近似）基于特征的技術(shù)比基于外觀的技術(shù)更耗時(shí)。實(shí)時(shí)考勤管理系統(tǒng)需要較低的計(jì)算處理時(shí)間。因此，在測(cè)試系統(tǒng)中使用三種基于外觀的面部識(shí)別技術(shù)，例如Eigenfaces，F(xiàn)isherfaces和LBP。Fisherfaces和eigenfaces技術(shù)具有不同[13]。根據(jù)之前的幾項(xiàng)研究，使用LBP方法進(jìn)行人臉識(shí)別可以在速度和辨別性能以及不同的光照條件[14,15]。通過尋找用于面部識(shí)別的圖像之間的相似性來計(jì)算歐幾里德距離。基于歐幾里德距離的特征面，F(xiàn)isherfaces和LBP計(jì)算的濾LBP，F(xiàn)isherfaces和Eigenfaces算法的最小歐幾里德距離。如果LBP算法的歐幾里德距離小于40;否則，如果Fisherfaces算法的歐幾里德距離小于250;否則，如果Eigenfaces算法的歐幾里德距離小于1500，則識(shí)別的面部被記錄為正確的第二級(jí)歐幾里德距離（對(duì)于，（對(duì)于，（對(duì)于特征臉）是以同樣的方式評(píng)估。如果也未滿足第二級(jí)條件，則過濾器返回錯(cuò)誤的匹配。第三，如果任何兩個(gè)算法給出相同的匹配結(jié)果，則正確記錄匹配。最后，如果沒有滿足條件，則優(yōu)先考慮LBP架構(gòu)旨在通過不需要額外設(shè)備來實(shí)現(xiàn)靈活性，移動(dòng)性和低成本。同時(shí)，其目標(biāo)是隨時(shí)為所有用戶提供訪問權(quán)限。因此，該系統(tǒng)為所有用戶提供實(shí)時(shí)考勤管理系統(tǒng)。四、實(shí)施和結(jié)果使用以下平臺(tái)。云服務(wù)器具有2.5GHz，4核CPU，8GBRAM和64位操作系統(tǒng)容量?；贠penCV實(shí)現(xiàn)了Viola-Jones人臉檢測(cè)算法和特征臉，F(xiàn)isherfaces和LBP人臉識(shí)別算法。iOS和ANDROID都進(jìn)行了測(cè)試。在真實(shí)的教室中進(jìn)行了40次不同的出勤監(jiān)測(cè)測(cè)試，包括11名學(xué)生，并檢測(cè)到264名學(xué)生的面部。表II和III顯示了與歐氏距離相關(guān)的所有三種不同類型的測(cè)試算法的檢測(cè)和識(shí)別準(zhǔn)確度。根據(jù)每個(gè)間隔的準(zhǔn)確率安排3種算法的優(yōu)先級(jí)排序。在測(cè)試結(jié)果中，分別檢測(cè)到特征臉，F(xiàn)isherfaces和LBP的123,89和85個(gè)錯(cuò)誤識(shí)別。在開發(fā)的過濾系統(tǒng)的幫助下，錯(cuò)誤識(shí)別的數(shù)量減少到65個(gè)。在40個(gè)實(shí)施的考勤監(jiān)測(cè)測(cè)試中，10個(gè)進(jìn)行了步驟I1張面部照片，當(dāng)數(shù)量為20時(shí)進(jìn)行在步驟II中，面部照片增加到3，并且在步驟III中在數(shù)據(jù)庫中使用超過3張面部10IV顯示了獲得的結(jié)果。測(cè)試考勤監(jiān)控過程中最重要的限制是隨著攝像機(jī)與學(xué)生之間距離的增加而降低成功率。關(guān)于坐在前排座位上的學(xué)生的結(jié)果與坐在后排的學(xué)生的結(jié)果相比更準(zhǔn)確。其次，由于在拍攝照片時(shí)由振動(dòng)引起的模糊，準(zhǔn)確率可能已經(jīng)降低。第三，在某些情況下，學(xué)生面部的一部分可能被坐在他/她面前的另一名學(xué)生所覆蓋，這可能妨礙成功的面部識(shí)別過程。由于教室照片是在不受控制的環(huán)境中拍攝的，因此照明和姿勢(shì)可能在很大程度上影響準(zhǔn)確率。開發(fā)的過濾系統(tǒng)使這些影響最小化。為了提高準(zhǔn)確性，也可以使用姿勢(shì)容忍的人臉識(shí)別方法[16,17]。五、結(jié)論本文提出了一種靈活，實(shí)時(shí)的基于人臉識(shí)別的移動(dòng)考勤管理系統(tǒng)。已經(jīng)開發(fā)了基于歐幾里德距離的過濾系統(tǒng)，該過濾系統(tǒng)由特征臉，F(xiàn)isherfaces和LBP計(jì)算。所提出的系統(tǒng)消除了額外設(shè)備的成本，最大限度地減少了考勤時(shí)間，并允許用戶隨時(shí)隨地訪問數(shù)據(jù)。智能設(shè)備非常易于用戶進(jìn)行課堂出勤監(jiān)控。教師，學(xué)生和家長可以毫無限制地實(shí)時(shí)使用該應(yīng)用程序。由于互聯(lián)網(wǎng)連接速度一直在穩(wěn)步增長，因此可以向服務(wù)器發(fā)送高質(zhì)量，大圖像。此外，服務(wù)器的處理器容量也在日益增加。通過這些技術(shù)發(fā)展，所提出的系統(tǒng)的準(zhǔn)確率也將提高。人臉識(shí)別可以通過其他人臉識(shí)別技術(shù)進(jìn)一步測(cè)試，例如支持向量機(jī)，隱馬爾可夫模型，神經(jīng)網(wǎng)絡(luò)等。另外，一旦處理器容量充分增加，就可以在智能設(shè)備上執(zhí)行檢測(cè)和識(shí)別過程。參考文獻(xiàn)[1]L.Stanca,"TheEffectsofAttendanceonAcademicPerformance:PanelDataEvidenceforIntroductoryMicroeconomics,"J.Econ.Educ.,vol.37,no.3,pp.266,2006.PaniandKishore,"AbsenteeismandperformanceinaquantitativemoduleAquantileregressionanalysis,"JournalofAppliedResearchinHigherEducation,vol.8no.3,pp.376-389,2016.[3]U.Thakar,A.Tiwari,andS.Varm
